Field Marshal Tantawi between the youth and the 'Brotherhood'

For the first time in Egypt, the military council is in confrontation with the youth. There are no more calls for trials, change of prime ministers or election vows. The main demand is now the end of military rule and the transfer of power to a civilian government. Although it is a logical and expected demand, the really confusing question is why do the protesters target the military council with only a few days left before the parliamentary election, which was one of the demands of the revolution?
